Be it known that We, GEORGE lll. Mrx'rnn and JOHN V. Honsrnin, respectively, citizens ot the United States. residinget Moline9 in the county of Peel( Island and State oi lllinois. here in'xfented eert in newY and use- 'iful Improvements in Cultisfutors, ot Whieh the Yteilw-.ifmg' is a speeiiieation, reference being had therein to the aeoonu anjving draw-- ing.

@ur inventionr relates to inore pertioulaiily to the when. thereof.

The object otl our invention is to provide a simple f-etive ineens tor shitting the wheels and axles to eonipesate, not only for 'variation in the Weight oli the draft attaelnnent which is el inged aeeording to the nxunber oil horses util ed to draw the Icultivater.y but lilvewise Afor Variation in the weight er operators, se that down pressure upon the nerks oli the horses is practically eliminated.

The inaiu traine consists o' a iront bar l and a rear bar 2 spaced apart and rigidlyv connected by side bars 3 and e, and bars 5, 6, 7 and 8. A seat support 9 is secured to the bars 7 and S and to the rear ,traine bar 2 and has a seat l0 mounted thereon. Draft poles Ill and l2 are secured to the bars 5 and (i and to the Ylraine bar l. Projecting Yli'or\-f:irdly treni the traine bar l. and secured thereto, are braelets 1&3 mul lei; on which are pivotully mounted doubletrees l5 and i6, Carrying singletrees l? on their outer ends. and to their inner ends is oonneeted a singletree i8. Gangs et cultivating devices 19 are carried by suitable supports Connected to the traine.

thereof lere-achete 2O having' Vertical sleeves 21; 'the Wheels 22 are mounted on laterally extending end portions 23 of rearwardljiV prejeotir parts 2e of axles haring vertie/ spinrll The spindles 25 are jouri u in b fiings 26 parallel With the slee res 2l and :ire rotatably supported thereon 'by pins 2T which extend through arms 28 und 29 on the bearings 26 and through the sleevesl 2l; the arms 29 extending over the toi s of the sleeves 2l, and the arnis 28 extending beneath the lower end thereof. Collars 30 on the spindles 25 are interposed between the bases et the bearings 26 and the rearwardly projecting parts 24 of the axle.

@n the upper ends of the spindles 25 are rigidly mounted arins 3l projecting 'for- Wardly and Connected by rods 32 to a suitable mechanism 'tor angling the Wheels. 0n

the front of 1the sleeves 21 are lugs 33 and on the rear thereof are similar lugs 334. Un the bearings 2G are lugs registering with either ot' the lugs 8B and Se and seourable thereto in a manner und for a purpose bereetter described.

is shown in the drawings the eultivator is erpxipped wi th a irait device tor three horses and the bearings 2G are reu 'ward oli 'the hruelcet sleeves and secured in place by suitable bolts L,use-ed through periioratiens in the lugs Pe und lillhen a four horse (l1-att device substituted tor the three horse shown7 or a heavier driver is to operate the machine the additional weight will cause pressure upon the necks oi the horses; to compensate for this increased Weight we shift the axles forwardly so that the Weight of the entire ineehanisin is brought closer to the axis of the Wheels. ln shifting' the axles and Wheels We remove the bolts in the lugs 8st andL 85 then swing the bearings 26, which pivotally supported on the brackets 20 bj; the pins 27 passing through the arnis 28 end 29 and the sleeve 2l; the bearings are swung laterally until the lugs 35 thereon are in Contact with the lugs 3S ou the trout oli the braoe'ts 207 and are secured in place by bolts passed through the lugs 533 and 3:3, the spindles 27 and bearings 2G being new in a position 'orward of the sleeves 2l.

llllhen the bearings 26 are swung as just deser'ibed, the anis ofthe Wheels and the niain iranie are brought closer together, the spin d les being always vertical and parallel with .the pins 27 and consequently always have the same angular relation with the frame@ The wheels 22 maintain their position in relation to the line of draft, in substantial parallelism therewith, during the swinging of the bearings 26, being controlled by the arms 3l and the rods 32 pivotally connected therewith and with either a fixed or adjustable part of the machine. With the swing of the bearings 26 the wheels 22y are moved outward and are moved inward upon the Continuation of the swinging movement of the bearings 26 until the latter are secured in place as described. rlhe arms 31 moving forwardly with the forward swing of the bearings 26, the rods 32, swinging on their pivoted inner ends, move the ends of the arms 3l, to which they are connected, outwardly tending to give the wheels 22 an voutward forward flare, an objectionable feature which is compensated for in the following manner; the lugs 33 and 34 are of the same depth or thickness at the -bearings 26, but from these points the lugs 33 have an outward inclination, the depth or thickness at their forward ends. is consequently greater, the difference in the depth at their forward ends over the depth at the bearings 26 being equal to the outward movement of the ends of the arms 3l. when the latter are moved forwardly in swinging the bearings 26, soy

that when the latter are secured to the lugs 33 the wheels 22 are in the same substantially parallel relation with the line of draft as they were before, as clearly illustrated in Figure ll.

`When it is desired to adjust the wheels to compensate for any irregularity in their relation to the line of draft due to strain or other causes, or if it is desired to give the wheels a slight gather, the rods can be unhoolred from their inner end connection and turned in the castings 3G which are pivotally supported on` the free ends of the arms 31 and held in place by cutters or `pins 38. Or'the ootters or pins 38 can be removed and the castings 36 can be lifted from the arms 3l and turned upon the rods 32 until the desired adjustment is effected, the eastings 36 are then replaced on theV arms 3l, j

their spindles 37 fitting in suitable openings therein, and again secured in place by the cotters or pins 38. The openings in the castings 36 through which the rods 32 exl. ln a wheeled cultivaton the combina--` tion of a frame, axles carried by vertical bearings on the frame, said bearings being` pivotally supported on theframe and adapted to be swung bodily in a horizontalarc to move the axles fore and aft relative to the frame.

2. in a wheeled eultivator, the Combination of a frame, vertical bearings movably supported by the frame, axles having spindles journaled in said bearings, said bearings adapted to swung in a horizontal are to adjust the axles bodily fore and aft relative to the frame, and means for securing the bearings-to the frame.

3. ln a wheeled cultivator, the combination of a frame, axles having vertical spindies journaled in bearings on the frame, said bearings being pivot-ally supported on the frame and adapted to be swung bodily in an arc to move the axles fore and aft relative to the frame.

Li. ln a wheeled cultivaton-the combina- .tion of a frame, axles having substantially ,vertical spindles journaled in movable bearings on the frame, said bearings being pivotally supported on the frame and adapted to be swung laterally in the are of a circle to adjust the axles bodily forward or rearward of the pivotal support of the bearings, and means to secure said bearings in either position. l

5. ln wheeled eultivator, the 'combination of a frame, axles having vertical spindies journaled in movable bearings on the frame, said bearings adapted to beV swung laterally in the arc of a circle to move said axles forward or rearward, and means tof adjust the wheels angularly to the line of draft, said adjustment remaining Constant irrespective of the lateral swing of said bearings.

In testimony whereof we aiiiX our-signatures, in presence of two witnesses.
